While the respite from the heat will be welcome, safety measures during the installation process mean that the medical ward will be closed although the emergency department remains open.

The hospital usually admits one patient a day at this time of year on average, but the hospital had no inpatients on Friday ahead of work starting, so no initial transfers were required. Cases seen in emergency over the weekend either required no further treatment or needed specialist treatment at other centres.

Peter Williams, General Manager, Tablelands Sector said the air conditioning would be fitted just in time for the hottest part of the year.

"We know that this upgrade is something the community has been looking forward to for some time," he said.

"While work goes ahead, the emergency department will remain open around the clock, however, the medical ward will temporarily close from Monday, 9 November to Sunday, 29 November.

"The reason for this is precautionary to ensure any asbestos which needs to be removed from the ceiling cavity can be done so safely by licensed contractors and transported off-site.

"While the ward is shut, any patients who require admission for ongoing care will be transferred to the nearest hospital possible that can best support their medical needs.

"Before reopening the ward, it will obviously be thoroughly cleaned and certified by an occupational hygienist to ensure all work carried out complies to the highest safety standards.

"While our first preference is to care for Tenterfield people in their own hospital, the next three weeks will pass quickly, and our patients, visitors and staff will enjoy air-conditioned comfort for many years to come."
